Expertly engineered for MX and Enduro riding, the S-M3 Solid Helmet is a lightweight off-road solution designed for superior impact protection and rider comfort. Featuring a thermo-injected shell with a patented visor release system and a low-friction internal coating, it effectively reduces rotational acceleration forces during impacts. This ECE 22.06 certified helmet includes a maximized ventilation system with 17 ports and integrated hydration tube channels.

Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and engineered thickness to provide the optimal balance of lightweight performance and impact protection (1430g ECE / 1460g DOT).
Maximized Ventilation: Optimized airflow and heat exchange via 10 intake vents and seven exhaust ports for superior rider cooling.
Rotational Acceleration Force Protection: Patented low-friction coating on the internal EPS liner acts as a slip plane to reduce rotational forces during oblique impacts, mimicking the brain's natural defenses.
Patented Visor Release: Engineered system ensures the visor detaches with a pre-determined force to minimize neck strain and rotational energy during an impact.

Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
Five-piece EPS inner liner featuring four different densities for optimized impact management and performance.
Integrated hydration tube channels within the cheek pads for seamless performance and convenience.
Comfort liner manufactured using recycled materials to reduce environmental impact.
Customizable fit via interchangeable crown and cheek pads, available as genuine spare parts in various thicknesses.

Shell thickness and structure optimized in the chin area for superior impact performance, exceeding standard homologation requirements.
Inner and outer surfaces engineered to minimize the effects of oblique impacts.
Emergency Release System with removable 3D contoured foam cheek pads for safe helmet removal.
25mm soft textile chin strap for secure and comfortable fastening.
Stainless steel D-rings ensure a consistent and tight fit.
Certified to ECE 22.06 homologation and DOT standards for worldwide use.
